$++$ A website requires that passwords do not contain whitespace. For each character in codeStr that is whitespace, replace the character with $\text{'}*\text{'}.$

Ex: If the input is $4$ T K$,$ then the output is:

Updated password: $4*$T$*$K

Note: isspace$()$ returns true if a character is whitespace, and false otherwise. Ex: isspace$(\text{'}\text{'})$ returns true. isspace$(\text{'}$a$\text{'})$ returns false.
